1. Chromatography of rat-liver lipids on a column of silicic acid or a mixture of silicic acid and Hyflo Super-Cel, with chloroform-methanol mixtures, gave monophosphoinositide-containing fractions which were invariably contaminated by the presence of nitrogen-containing phospholipids. The behaviour of the inositide was extremely sensitive to column loading and the results with different batches of silicic acid were not reproducible. 2. However, when chromatography on an alumina column was used, the solvent system chloroform-methanol-water (23:23:4, by vol.) completely eluted the neutral lipids, choline-containing phospholipids and phosphatidylethanolamine. An increase of the water content of the solvent to 14% (by vol.) then led to the elution of the monophosphoinositide component, now free from nitrogen-containing phospholipids, but still contaminated by the presence of a phospholipid, which from its properties was taken to be polyglycerophosphatide. 3. Most of the polyglycerophosphatide could be removed from a rat-liver lipid extract by silicic acid chromatography with chloroform-methanol (19:1, v/v). The other phospholipids were then eluted and applied to an alumina column, whereby a monophosphoinositide fraction of much greater purity was obtained. 4. Further purification of the monophosphoinositide was achieved by chromatography on a mixture of silicic acid and cellulose powder. The final product was virtually pure by thin-layer chromatography and gave the expected analysis for monophosphoinositide.
